When a high-speed dubbing processing start operation is performed by the remote control signal RS or the operation signal PS, a re-recording start processing operation is performed in step ST1. In the re-recording start processing operation, the movable terminal 203c of the signal switch 203 is set to the terminal 203a side by the switch control signal CS-3. Thereafter, the audio signal to be re-recorded by the disk reproducing unit 14 is reproduced at N times the standard speed. The disc recording / reproducing section 13 performs recording at N times the standard speed.

Here, in the N-times speed reproduction, when the reproduction speed in the disk reproduction unit 14 is set to the N-times speed, the reproduction speed is different from the standard speed and the control of the disk reproduction operation becomes complicated. The reproduced sound output from the sound 23 may be unpleasant. To prevent such a case, the switch control signal C is used during re-recording.
The movable terminal 201e is automatically set to the terminal 201a side by S-1 and the reproduced audio signal Stu from the tuner unit 11 is supplied to the volume control unit 21 as the reproduced audio signal Sa. Alternatively, the movable terminal 201e is automatically set to the terminal 201b side, and the reproduced audio signal Std from the tape deck unit 12 is supplied to the volume control unit 21 as the reproduced audio signal Sa.

Is supplied to the volume control unit 21 so that the reproduction sound at N times speed can be output from the speaker 23. Also,
If it is not desired to listen to a broadcast program or other audio recorded on the magnetic tape during re-recording, the mute operation may be performed by controlling the volume control unit 21 with the volume control signal CV.

In step ST2, it is determined whether or not the re-recording of the desired audio signal has been completed. Here, when all the desired audio signals have not been reproduced, the process returns to step ST2, and re-recording of the audio signals is continued. When all the desired audio signals have been reproduced and re-recording has been completed, step S
Proceed to T3. In step ST3, a re-recording end processing operation is performed. That is, the reproduction operation in the disk reproduction unit 14 and the recording operation in the disk recording / reproduction unit 13 are terminated by the control signal CT, and the process proceeds to step ST4.

In step ST4, since the audio output based on the audio signal being re-recorded is not performed, the recording confirmation processing operation is performed to notify the completion of the re-recording and confirm the recording state on the recordable optical disk. Do. In this recording confirmation processing operation, the movable terminal 202c is set to the terminal 202a side by the switch control signal CS-2, and the disk recording / reproducing unit 13 is controlled by the operation control signal CT, for example, to end the re-recorded audio signal. The part is reproduced at a standard speed for a predetermined time, and the process proceeds to step ST5. When the mute operation is being performed by the volume control unit 21, the mute operation is canceled by the volume control signal CV. At this time, a reproduced sound based on the audio signal recorded on the recordable optical disk is output from the speaker 23. Therefore, it can be easily determined that the re-recording has been completed.

When the process proceeds from step ST4 to step ST5, it is determined in step ST5 whether or not the confirmation processing operation has been completed. Here, if the reproduction of the re-recorded audio signal for the predetermined time is not completed, step S
Returning to T5, a reproduced sound based on the audio signal recorded on the recordable optical disk is continuously output. When the reproduction for a predetermined time is completed, the output of the reproduction sound is stopped and the high-speed dubbing process is terminated. Since the audio output based on the audio signal re-recorded on the recordable optical disk is performed in this manner, the recording state on the recordable optical disk can be easily confirmed.

As described above, according to the above-described embodiment,
During high-speed dubbing processing using digital audio signals, during re-recording, analog audio signals obtained by receiving a broadcast program or analog audio signals obtained by reproducing another recording medium Since audio output based on the signal is performed,
Unpleasant sounds can be prevented from being output. Also,
When the re-recording is completed, the re-recorded audio signal is reproduced on the recordable optical disc, and an audio output based on the reproduced audio signal is performed. It can also be checked whether the processing was performed correctly.

Further, since the dubbing process is performed by the digital audio signal, the analog audio / audio signal Stu obtained by, for example, the tuner unit in the tape deck unit 12 during the dubbing process may be analog-recorded on the magnetic tape. it can. The recording medium used for the dubbing process is not limited to the optical disk, but may be a recording medium using magnetism, a recording medium using a semiconductor, or the like.

[0029]

According to the present invention, during the re-recording of the audio signal from the first recording medium to the second recording medium, the audio output based on the audio signal re-recorded on the second recording medium is performed. Otherwise, when the re-recording is completed, the audio signal re-recorded on the second recording medium is reproduced for a predetermined time and the audio is output. For this reason, the end of the dubbing process can be easily determined, and whether or not the dubbing process has been correctly performed can also be confirmed. During re-recording, audio output based on an audio signal different from the audio signal being re-recorded is performed. For this reason, it is possible to prevent output of unpleasant sounds, and it is possible to listen to other reproduced sounds such as broadcast programs using the re-recording period.
